SPECIFICATION formingpart of Letters Patent No. 716,766, dated December 23, 1902.

Application filed OctoherlO, 1901. Serial No. 78,216. (No model.)

To all whont it may concern.-

Be it known that LWALTER M. SCHWARTZ, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Treating Tobacco, Yarn, or Similar Material, of which the following is a specification. My invention relates to certain improvements in machines for treating tobacco, yarn, ID or similar material.

The main object of my invention is to so construct a machine in which artificial heat is circulated in aclosed compartment that access may be had to the material under I 5 treatment at diiferent points throughout the length of the machine.

Afurther object of the invention is to prevent the overheating of the material under treatment should either the mechanismfor 2o conveying the material through the machine or the blades be stopped for any cause.

'In the accompanying drawings, Figure l is a side elevation of one form of machine for cooling, heating, and ordering tobacco, illus- 2 5 trating my invention. Fig. 2 is a plan view of the same. Fig. 3 is a sectional plan view of a portion of the machine on the line 3 3, Fig. 4. Fig. 4 is a vertical sectional view on the'line at at, Fig. 3. Fig. 5 is a section on the line 5 5, Fig. 3; and Fig. 6 is a section on the line 6 6, Fig. 3.

Ais the casing of the machine, and in the present instance there is a drying-compartment A, a cooling-compartment A and ordering-compartments A A Extending through these compartments in the present instance is an endless belt conveyer B, driven in any suitable manner and supported at intervals by rails b 19, secured to the par- 0 titions (to. in any suitable manner. These partitions a a. separate the side compartments O O at each side of the apparatus from the central compartments, and in the upper portion of the central compartment of each section is a circulating-fan O, driven in any suitable manner in the present instance by a longitudinal shaft 0*, extending the full length of themachine and geared to the fanshaft 0 by bevel gear-wheels.

. In each of the-side compartments 0 O are steam-pipes E for heating the air that circulates through each of the sections. In order to provide sufficient heat to maintain the air in circulation at the proper temperature, all the available space in the side compartments is 5 5 taken up by the pipes, so that access to the to- 'terial under treatment can be examined. I

form in the present instance at the point where one section joins another recesses F, one at each side of the apparatus, and these recesses are preferably of sufficient width that the operator can stand in the space. These recesses extend to the rails b, upon which the belt travels, and doors f are provided in the casing at the recesses, so that the operator can open the door and extend his arm over the belt carrying the material and can examine a large body of the same. In narrow machines it may be only necessary to have the recesses on one side of the machine, and in this case the operator can extend his arm across the full width of the belt; but in wide machines it is preferable to have the recesses on both sides of the machine, so that the operator can examine any portion of the material on the belt. These recesses F- do not materially out down the compartments O O, in which the heating-pipes are situated, and do not interfere with any of the operating mechanism 0t the machine.

Directly above the compartments (l of the drying -section of the machine are doors I, which can be opened to allow the heated air to escape directly from the compartment 0 as it is heated by the steam-pipes when the conveying mechanism or fans are not in motion, so as to prevent overheating of the material under treatment when the apparatus is at rest.

It will be understood that while I have shown an endless-belt conveyer for carrying the material through the machine in the present instance any suitable conveyer can be used, depending altogether upon the material to be treated, and that in treating tobacco, for instance, the compartments are so arranged that two shall be drying-compartments, one a cooling-compartment, and two others ordering-compartments, as shown in the drawings, while in treating yarn the compartments may be drying and cooling compartments only, the main object being to gain access to the interior of the machine during the time that the material is under treatment.

In some machines one recess may only be necessary, while in others a number of recesses may be necessary.

The fans for circulating the heated air may be arranged at anyv point in the machine desired without departing from the main feature of my invention.

I claim as my invention- 1. The combination in a machine for treating tobacco, yarn and like material, of a casing, means for conveying material through the casing, two or more chambers projecting at one side of the casing, spaces between the chambers so that access may be had to the material being conveyed in the casing, heating means in the projecting chambers, and means for circulating the heated air through the central casing and side chambers, substantially as described.

2. The combination in a machine for treating tobacco, yarn and like material, of a longitudinally-arranged casing having a series of compartments, a conveyor in said casing extending through the several compartments, chambers projecting from the casing opposite each compartment, said chambers being so spaced apart as to form recesses so that access may be had to the material being conveyed in the casing, and means for circulating air through the casing and the side chambers, substantially as described.

3. The combination in a machine for treating tobacco, yarn or like material, of a casing divided into a series of sections, each section having acentral compartment and side oompartments, heating-pipes in each of the side compartments of each section, a conveyor traveling through the central compartment, means for operating said conveyer, a circulating-fan in each compartment situated above the conveyer, the casing being recessed on each side and at each point where one section joins another section, said recess extending to the central compartment, an opening in the casing, and a door closing said opening, so that when the operator is standing in the recess access may be had to the material carried by the conveyer, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
